Pros
As a former schoolteacher, I applaud The Coder School for not waiting for schools to catch up with the times and teach young people to code. As a Code Coach you have pretty much total freedom in what projects you work on with students. But students/parents have total freedom to switch to another coach, so you'd better do something fun, interesting and useful. Sometimes I'd do games, sometimes solving puzzles, and sometimes cloning an artsy sketch I found on Twitter.
Cons
Don't expect it to be a career, it's a part-time job (but one I find extremely satisfying). There's no deal-breaking problems: just sometimes a kid is unpleasantly surprised at how much work it is to code something he or she thought would be easy. Most coders find that inspiring but some kids are used to swiping their iPads and won't push themselves.
